State ministers Kala Venkat Rao, D. Umamaheswara Rao, Nara Lokesh, Kollu Ravindra, MPs and state legislators and leaders of Telugu Desam Party (TDP) joined him in the fast at the massive programme organised by the state government.
Naidu's fast is to demand the Centre to accord special category status to the state and fulfil all commitments made at the time of bifurcation of Andhra Pradesh to carve out Telangana state in 2014.
Last month, the TDP pulled out of BJP-led National Democratic Alliance (NDA) to protest its refusal to give special status to the state. Naidu alleged that Prime Minister Narendra Modi has gone back on the promises he made in 2014 elections.
Naidu has appealed to people to observe the fast against the Central government's attitude, instead of celebrating his birthday.
Expressing solidarity with the Chief Minister, leaders and workers of TDP and various organisations are observing the fast across the state. State ministers were also on hunger strike in their respective districts.
